BOTTLE Filed may 5, 1930 Patented Aug. 11, 1931 JACOB W. CBEHRENDT, OFSAN FRANCISCO, CALIFORNIA BOTTLE Application led May This inventionrelates tto bottles as us/ed particularly in connection with medicinesand it has `for its objects a special formation of the bottle neck and aclosure therefor which 5 will be better adapted to use with liquidmedicines and aidin the accurate dispensing of the same andtransferringfrom bottle to bottle.

Also such a bottle which will have a screw lo cap et be free from theobjections to screw cap ottles when applied to pharmacists use, andwhich will avoid contamination of the medicament with the cap, or itstendency to run down over the threads of the bottle when pouring theliquid therefrom.

In the drawing accompanying this application the figure is a frontelevationof a glass bottle with the neck and sealing cap shown insection so as to clearly show the improved construction. l

In further detail the body of the bottle 1s shown at l and a cap 2screwed over its neck.

A This cap is of tubular form and is made of non-corrodiblemetal or ofsome non-metallic substance like Celluloid, vulcanite, bakelite, etc. Itis flat on top, threaded at its lower end at 3 and formed with aslightly enlarged recess at 4 adjacent its top so as to receive andretain a tightly fitting disk 5 of resilient sealing material such as acardboard or cork disk preferably covered on its underside with a sheetof paraiiined paper, cellophane, or the like as at 6, the covering paperbeing wrapped over the edges of the disk as indicated, and for some usesI preferably cement the disk in place in the cap.

This cap in combination with the partlcular form of the bottle neck iswhat constitutes my invention and it will be observed that the tubularcap extends straight down to just clear the outer lip 7 of the bottle,that this lip 7 is reduced to a relatlvely thin-cornered edge so as tomake it possible to pour out a single drop if desired, also that theouter edge of the lip is slanted downwardly from .the upper end of theneck which is provided with a substantially ilat space at 8 againstwhich the disk seats, and that the inside throat of the bottle roundsout smoothly to this flat spot, while the inside of the 1930.

neck continues downward in a substantially unbroken curve to theinterior of the bottle. This internal formation makes it possible toprecisely control the flow of the liquid.

Another feature of great importance is the inwardl curveof the outsideof the neck at 9 for a relatively long distance above the threads with aminimum length of substantially half the diameter of the lip whereby alltendency of back-flow of the liquid is prevented and the bottle mayeasily be balanced on the edge of a beaker, measuring glass or otherbottle in accurate dispensing of medicants therefrom.

The upper portion of the inside of the neck is slightly tapered at 10 tosuit a standard cork in case the cap becomes lost or injured.

As an aid to screwing or unscrewing the cap it may be provided with fineutes around its exterior as at 11.

At rst thought myvbottle as above described might be thought to vary butlittle from an ordinary screw cap bottle, but upon re ection it will beseen to be an improved combination which has been a plain unmetrequirement in the pharmacists laboratory for years, as all attempts tointroduce screw-capped bottles have thusv far met with disfavorbecause- 1. The bottles had no pouring lip.

2. The former construction prevented the use of a thin pouring lip.

3. There was no at top for sealing properly against a disk.

4. There `was no hooked portion at a distance suiiiciently below thepouring edge for balancing the bottle upon the' rim of a receivingbottle or vessel.

5. The threads ran clear up to the top of the neck or were so high up asto cause the liquid to run back upon them so as to dirty the wholebottle and cause corroding of the lid.

An examination of the shelves of a dispensing pharmacist this very daycorroborates the above, and the stock bottles provided with screw capsall suffered from the objectionable features above mentioned.

Therefore, as my bottle is the outcome of much experimenting in thisfield of work and is a practical, simple, perfect sealing and perfectpouring bottle with dispensing lip and with a plain balancing neck abovethe threads avoiding any run-back of liquid and with a neck which iseasily wiped o' to keep it clean so that no liquid will come in contactwith the cap to corrode same if of metal, and pharmacists and physiciansto whom it has been shown are enthusiastic about it, I believe thecombination to be new and useful and to ll a decided requirement inbottles for the purpose intended.

I claim:

1. A bottle having a pouring neck and an outwardly directed pouring liparound its upper end, threads around the neck at a point spaced belowthe pouring lip, a relatively long unthreaded portion between the lipand the threads, said unthreaded portionV being curved inwardly tosmaller diameter to form a balancing neck. .Y

2. A bottle having a pouring neck and an outwardly directed pouring liparound its upper end, threads around the neck at a point spaced belowthe pouring lip, a relatively long unthreaded portion between the lipand the threads, said unthreaded portion being curved inwardly tosmaller diameter to form a balancing neck, the extreme upper edge ofsaid neck being substantially flat to contact a sealing disk.

3. A bottle having a pouring neck and an outwardly directed pouring liparound its upper end, threads around the neck at a point spaced belowthe pouring lip, a relatively long Unthreaded portion between the lipand the threads, said unthreaded portion being curved inwardly tosmaller diameter to form a balancing neck, the extreme upper edge ofsaid neck being substantially iat to Contact a sealing disk, and theupper edge of said pouring lip being slightly lower than the flattenedupper edge of the neck.

4. A bottle having a pouring neck and an outwardly directed pouring liparound its upper end, threads around the neck at a point spaced belowthe pouring lip for screwing a closure cap over the end of the neck, arelatively long unthreaded portion between the lip and the threads, saidunthreaded portion being of smaller diameter than the lip and with aminimum length from the lip to the threads of substantially half thediameter of the lip.
